Application July 3, 1937, Serial No. 151,793

15 Claims. (01. 104-258) a The. invention relates to car stops adapted to be placed at a selected point ontop of a car rail and clamped thereto to engage the wheel of a car to limit the movement of the car along the rail.

One of the objects of the invention is to facilitate the application and removal of a stop of the type referred to.

Another object of the invention is to simplify such stop structure and to minimize the cost thereof. v

These and other detailed objects of the invention will be apparentfrom the following description of the device, reference 1 being had to the accompanying drawing, in which- Figure 1 is a front elevation of. the stop showing the same in position on a rail.

Figure 2 is a similar elevation showing th holding device in released position. 1

Figure 3 is a side elevation of the structure as shown in Figure l.

, Figure 4 is a similar elevation illustrating a modified structure.

Figure 5 is a vertical section taken approximately on the line 5-5 of Figure 4.

The device illustrated in Figuresl, 2 and 3' comprises a body structure I, having a base 2 adapted to rest upon the top of a head of a track rail 3, the body including forwardly and rearwardly facing surfaces adapted to contact with the wheel of a car mounted upon the track. Lugs 4 and 5 depend from body I, and lug 4 includes'a jaw 6 arranged to project beneath the rail head. The other lug 5 has its inclined edge shaped to permit the device to be moved into position on 1 the rail head with jaw 6 opposing the underside of the head as shown. I

A rod 1 is passed through an aperture 8 in the body structure and is then bent at right angles at the sides of. the-body to form a lever handle 9 and a hook it respectively. When the handle is raised, as shown in Figure 2, hook ID will be moved away. from jaw B so as to permit the device to be applied to a rail or removed therefrom. When the handle is lowered, as shown in Figure I, hook ill will be moved towardsjaw B to hold the "device onto the rail.

A coiled spring H is compressed between a bracket l2 onhandle 9 and the opposing face of the body, beingpositioned onthe latter by a projection l3. Spring H and the rod structure have a snap action whereby the handle and hook are yieldingly held in one of the two positions indicated, pins 14 serving to limit the movement of the handle in opposite directions from an intermediate neutral point. a

If desired, a padlock l5 may be applied through an aperture IS in, the body to prevent upward movement of handle 9 and thereby maintain hook l0 beneath the rail head and prevent removal of the device from the rail except by an authorized person.

In the modification illustrated in Figures 4 and 5, the body structure isjmade of. a plurality of relatively thin plates having substantially the same contour as'the cast or forged body structure shown in Figures 1 to 3. The outer plates 21 and 22 have an aperture corresponding to aperture 8 in the body structurepreviously described,

. and the

intermediate plates

23, 24 and 25 are The operating lever 39 corresponds to that shown in Figures 1 to. 3 and may be given its final form before assemblywith the body structure if the plates comprising the latter are not secured together until the handle is assembled therewith. The two outer plates 2| and 22 may be passed separately over the hook end of the lever into the position shown in Figure 4, and the

intermediate plates

23, 24 and 25 may be inserted between plates 2| and 22 and moved transversely of the journal portion of the leverinto the position shown. All of the plates can then be riveted together, as indicated, to form a substantial body structure. r

In both forms of the invention, thebase off the stop is relatively narrow, longitudinally of the rail, and the wheel opposing face of the stop is relatively wide transversely of the rail. There is sufficient clearance between the rail head and lugs 4 and 5 and. jaw 6 to permit the stop to tilt from. its upright position longitudinally of the rail and to twist from its normal position with its wheel engaging face at right angles to the rail. Since the wheel engaging face of. the body extends laterally a substantial distance beyond the edge of the rail head, the body will first with and dependin tween opposed lugs 4 and '5 and between the jaw 6 and base 2. Thus the device is securely clamped to the rail and held against movement longitudinally thereof by rigid elements and independently of the movable latching element which merely serves as a retainer to temporarily hold the device upright and prevent its accidental dislodgment from the rail.

It is obvious that the device is very simply constructed and readily applied to the rail and secured in position by a single movement of the operating lever. When it is desired to remove the device, it is just as simply released. It is unnecessary to drill any holes in the rail or to utilize tools of any kind in applying and removing the stop. The device is readily operated in close quarters and is therefore particularly adapted for use on mine car tracks where there is relatively little clearance at the side of the track.

The device may be modified substantially'in appearanceand in detail construction from the arrangement illustrated and described without departing from the spirit of the invention and exclusive use of such modifications as come within the sc pe of; the claims is contemplated.

What is claimed is:

A car stopcomprising a block arranged to s up n the op of gaging elements, a rail engaging member rigid from said block, and a cooperating latch lever pivoted directly on said block at a point spaced from the wheel engaging elements and said member and including a hook movable into and out of position to engage the rail to hold the block thereon, there being spring means for yieldingly holding said latch and hook in, rail, engaging position or in released position.

2.
